場所がなくなって燃料面を圧迫し補給ができなくなる。(Prior art) As shown in Figure tjIJ8.9, a vehicle-mounted fuel tank a
is provided with a fuel supply pipe C that projects diagonally upward to enable fuel supply from outside the vehicle body. However, since the replenishment pipe C protrudes from the lower side of the inner top surface of the fuel tank a, when fuel flows into the upper end edge d of the part of the refueling pipe C that protrudes from the fuel tank a during refueling, the tank There is no place for the air at the top to escape, putting pressure on the fuel surface and making it impossible to replenish.

料補給量が少なくなる欠点がある。To eliminate this drawback, the inner end is opened at a higher position than the upper end d in the fuel tank a, the outer end is opened at the upper part of the replenishment pipe C, and the air is bent low between the inner and outer ends. A vent pleather chape e is provided. However, at the end of refueling, fuel flows back into the tube e and accumulates at the bend f as shown in Figure 9, making it difficult to remove the air during the next refueling. This has the disadvantage that the amount of refueling is reduced each time.

位置にする。(Embodiment) Figs. 1 to 5 show a first embodiment of the present invention, in which 1 is a fuel tank, and 3 is a position lower than the internal top surface 2 of the fuel tank 1 and diagonally upward from the side of the tank 1. The protruding refueling pipe 6 is the tube main body of the freezer tube 5 whose outer end is opened above the fuel pipe 3 which is located at a higher position than the projections 1 & 4 of the refueling pipe 3 from the fuel tank 1. Then, a substantially horizontal tube v7 is formed with the part entering the fuel tank 1 from the lower side of the upper edge 4 of the protrusion 4 into an extended shape, and the inner end of the tube v7 is placed on the side of the receiver tank 8 having a large volume. The receiver tank 8 of this embodiment, which is connected to the belly of the vehicle, is arranged in the direction of travel of the vehicle as shown in Fig.
The front edge in the direction of travel 11 will be provided. The rIi port 10 determines the maximum height of the liquid level W of the fuel tank, and the opening 10 is aligned with the planned highest liquid level of the fuel tank to open the fuel tank 1.
Fixed inside. The opening 10 is positioned higher than the upper edge 4 of the protrusion.

。In this embodiment, from the fuel supply pipe 3 to the fuel tank 1,
When the fuel is refilled inside, the amount of fuel exceeds the upper edge 4 of the protrusion and reaches the height of the opening 10 of the receiver tank 8, and the fuel flows into the inside of the tube 7 through the opening 10. At this height, it is no longer possible to replenish fuel, and the highest liquid level W is determined. At that time, the fuel is clogged up to the lower part of the outer end opening of the pleaser tube 5. (Fig. 3) After the maximum fuel level W has decreased due to consumption and the opening 10 has protruded relatively from the liquid level, the brake lever is depressed by depressing the brake lever while the vehicle equipped with the fuel tank 1 is running. When multiplied by , the liquid level W tilts due to inertia as shown in Figure 4,
A similar fuel slope occurs in the receiver tank 8, so that some of the backflow fuel slides up the slope 9 and is discharged into the fuel tank 1. Although the amount of backflow fuel discharged from the receiver tank 8 that occurs each time braking is applied is small, the time interval between refueling is long, and during that time the above-mentioned fuel discharge is repeated many times. If it is lower, the fuel stuck inside the breather tube 5 will be
As shown in the figure, the air flows into the fuel reservoir 11 of the receiver tank 8 and restores the air discharge function within the fuel tank 1.

ける。Fig. 6.7 shows a second embodiment, in which a discharge pipe 9a is provided with an upward slope from the upper surface wall of the receiver tank 8a in the direction of the arrow xh of vehicle travel, and an opening 10a is provided at the front end of the discharge pipe 9a. An air supply pipe 11a is provided from the upper wall to protrude higher than the highest liquid level of the fuel tank, and an air supply pipe 11a is provided from the upper wall to protrude from the lower end of the tube main body 6a of the breather tube 5a in an approximately horizontal direction. 7a and a fuel reservoir 12a is provided below the joint of the tube W7a.
本実施例のレシーバ−タンク８ａは燃料タンク１ａ内に
おいて、排出’ｆｆ ９ ａの開口１０ａが最高の液面
Ｗを決定するように取付ける。The receiver tank 8a of this embodiment is installed in the fuel tank 1a so that the opening 10a of the discharge 'ff9a determines the highest liquid level W.

例と同じである）。The fuel supplied from the fuel supply pipe 3a reaches the upper edge 4 of the protrusion.
When the user enters the fuel tank above point A and immerses the opening 10a in the fuel liquid level, the fuel flows back from the discharge pipe 9a to the receiver tank 8a, and this becomes higher than the fuel reservoir 12a and flows into the tube W.
When the height reaches the point where the connection port 7a is blocked, air discharge from the breather tube 5a stops (the rest is the same as in the first embodiment).

５ａのエアー排出機能を回復する。When the vehicle is braked while driving after the fuel has decreased from the highest level W, the liquid level tilts due to inertia as shown in Figure Pt56, and a portion is pushed out from the discharge port 9a to the opening 10a and drains into the fuel tank. By repeating this process, the air discharging function of the breather tube 5a is restored as shown in FIG. 8 in accordance with the first embodiment.
